hi everyone,
in thermodynamics, when we calculate the heat capacity in constant volume, we assume Cv=dQ/dT..
well, but at isothermal condition suddenly they came up with Cv=dU/dT...
so i am getting stuck with this concept how they replace dQ with dU?
i know U= internal energy is only a function of T, but what is the explanation behind it? please help with the derivation and clarification...
advanced regards.
